Used primarily in industrial applications, this chemical serves as a flame retardant in various materials, including plastics and electrical equipment. It enhances fire resistance, making products safer for use in environments where fire hazards are a concern. Additionally, it has been utilized in research settings to study the environmental impact and behavior of polychlorinated biphenyls (PCBs). Due to its persistence and potential toxicity, its use is now highly regulated and restricted in many countries. Efforts are focused on managing its presence in older equipment and mitigating its environmental release.
